not expected corexl settings

I have a cluster with two gateways with 6 cores running r80.40 take 91

Before I configured mdps, 3 cores were running the fw processes and the interfaces configured were running multiqueue as expected.

Then I configured mdps with two interfaces. These two interfaces are configured with cpu "all" and therefore overlap with the cores.

Why not the interfaces configured in the management plane are configure with multiqueue or with a specific cpu not shared with the fw processes?

sim affinity -l
eth0 : All
eth2 : All
eth3 : All
Multi queue interfaces: eth5 eth6

fw ctl affinity -l
Kernel fw_0: CPU 5
Kernel fw_1: CPU 2
Kernel fw_2: CPU 4
Daemon mpdaemon: CPU 2 4 5
Daemon fwd: CPU 2 4 5
Daemon in.acapd: CPU 2 4 5
Daemon lpd: CPU 2 4 5
Daemon in.asessiond: CPU 2 4 5
Daemon vpnd: CPU 2 4 5
Daemon wsdnsd: CPU 2 4 5
Daemon rad: CPU 2 4 5
Daemon usrchkd: CPU 2 4 5
Daemon in.geod: CPU 2 4 5
Daemon cprid: CPU 2 4 5
Daemon cpd: CPU 2 4 5
Interface eth5: has multi queue enabled
Interface eth6: has multi queue enabled

I have realized that those mgmt interfaces have a different driver "tg3" that doesn't support multiqueue 
The affinity configuration is auto, so those interfaces should be set to a free core not to all. Why I am getting these settings? Should I be worried?

cat $FWDIR/conf/fwaffinity.conf
# Process / Interface Affinity Settings
# -------------------------------------
#
# Each line shoud contain:
# 1. A type - 1 character. "i" for interface, "n" for process name, "k" for kernel instance.
# 2. An ID - interface name, process name, or kernel instance number.
# a. For interfaces, you can also write "default", and the setting would apply to any interface not
# mentioned in the file.
# 3. The desired affinity. Either:
# a. One or more CPU numbers.
# b. "all" - all CPUs are eligible.
# c. "ignore" - do nothing for this entry.
# d. "auto" - use any free CPU. A free CPU is one that doesn't appear in any line in this file,
# and doesn't run a worker thread.

i default auto

MDPS requires a minimum of 8 cores, and you say you have 6.
That may be why it’s not working.

@PhoneBoy  the limitation is 4 CPU's and 3 firewall instances

Hi @Luis_Miguel_Mig  'All' simply means it can use any of the CPU (only one can be really used)

Can you share the output of 'mq_mng -o'?

definition of auto and all at  $FWDIR/conf/fwaffinity.conf 

# b. "all" - all CPUs are eligible.
# c. "ignore" - do nothing for this entry.
# d. "auto" - use any free CPU. A free CPU is one that doesn't appear in any line in this file,

 

healthcheck script (sk121447) gives me a warning about overlapping workers and SNDs - meaning it is not good I guess

In R77, when the affinity is set to auto, the output of "fw ctl affinity -l -r " shows specific cores for my interfaces, not all.



[Expert@fw1:1]# clish -c "show configuration" | grep "mdps int"
set mdps interface bond0 sync on
set mdps interface eth3 management on
[Expert@fw1:1]# mq_mng -o
No multiqueue supported interfaces available
[Expert@fw1:1]# dplane
